March 24, 2016 Update: BSA's legal department has asked that I remove the links to the Cub Scout Leader How To Book.
The only place that I've been able to find the book is in hard copy format on ScoutStuff and in local Scout Shops. This is a newer edition that the one previously linked to. The cover is different, and there are minor revisions to the content.
At this point, the book doesn't seem to be available electronically. Hopefully, BSA will introduce the Kindle version soon.
I'm so sorry if this caused you any inconvenience.
I feel like I've hit the jackpot! I found a copy of the Cub Scout Leader How To Book online in a pdf format! I have a printed version that I purchased a few years ago, but it's in the bookcase upstairs–not very convenient. It's great to have an electronic version of it.
For those of you who aren't familiar with the How-To Book, it is full of games, activities, crafts, hikes, outdoor cooking recipes, skits, cheers, songs, magic tricks, special events and more.
To keep it handy, bookmark the link or download the file and save it to your computer.
Thanks for your understanding!
Yours in Scouting,
